in the attempt to continually improve my play, I was wondering if rake should be used beyond the two charges of DoC until the duration of your rune proc runs out (i.e. 4/5 combo points -> rune procs)? In other words, is the direct damage of a non-DoC buffed rake and the subsequent ticks of it worth it to make up for the 1/2 DoC-buffed rake(s) that would be used in the beginning.

In my experience if I I have a DoC rake already up once the 2 procs are eaten up I return to using mangle (or shred if I'm berserking). I don't think it's worth losing the 25% buffed rake to gain the difference in initial damage between mangle/shred and rake.
